Abstract: A lever-type connector simply and reliably shows whether male and female connector housings have been correctly fitted together. A posterior face of the female housing 16 has a cover 17. A lever 20 is provided with cam grooves 30 into which fit follower pins 32 of a male connector M and which is supported pivotably by axles 25 formed in the cover 17. The female housing 16 is correctly fitted within a hood 12 of a male housing 11 by pivoting the lever 20 from a start position to and end position. First ribs 40 are formed on the outer circumference of base ends 22 of arms 21 of the lever 20. Second ribs 45 are formed on left and right edges of a ceiling face 17A of the cover 17. When the lever 20 has been pivoted to the end position, these ribs 40 and 45 are aligned. Observing this alignment allows one to ascertain that the lever 20 is in the correct position.
